FXLA101 Datasheet | Fairchild Semiconductor

Features - Bi-Directional Interface between Two Levels: from 1.1V to 3.6V - Fully Configurable: Inputs and Outputs Track VCC - Non-Preferential Power-Up; Either VCC May Be Powered Up First - Outputs Switch to 3-State if Either VCC is at GND - Power-Off Protection - Bus-Hold on Data Inputs Eliminates the Need for Pull-Up Resistors; Do Not Use Pull-Up Resistors on A or B Ports - Control Input (/OE) Referenced to VCCA Voltage - Packaged in Micro Pak™ 6 (1.00mm x 1.45mm) - Direction Control Not Necessary - 100Mbps Throughput when Translating Between 1.8V and 2.5V - ESD Protection Exceeds: - 8k V HBM (per JESD22-A114 & Mil Std 883e 3015.7) - 2k V CDM (per ESD STM 5.3) Applications - Cell Phones, PDAs, Digital Cameras, Portable GPS Description The FXLA101 is a configurable dual-voltage supply translator for both uni-directional and bi-directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device remains in three-state as long as either VCC=0V, allowing either VCC to be powered up first. Internal power-down control circuits place the device in 3-state if either VCC is removed. The /OE input, when HIGH, disables both the A and B ports by placing them in a 3-state condition. The /OE input is supplied by VCCA. The FXLA101 supports bi-directional translation without the need for a direction control pin. The two ports of the device have auto-direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.
